4 Channel Conduction Cooled XMC, RS232/RS422/ RS485 programmable serial interface, P16 I/O

Manufacturer's part number :

TXMC376-20R

Manufacturer Tews Datentechnik

Tews Technologies GmbH

Description :

The TXMC376-20R is a conduction cooled Switched Mezzanine Card (XMC) compatible module offering 4 channels of high performance RS232/RS422/RS485 programmable asynchronous serial interface with P16 I/O. The serial channels can be individually programmed to operate as RS232, RS422 or RS485 full duplex/half duplex interface. In addition programmable termination is provided for the RS422/RS485 interfaces. After power-up all serial I/O lines are in a high impedance state. Each RS232 channel supports RxD, TxD, RTS, CTS and GND. RS422 and RS485 full duplex supports a four wire interface (RX+, RX-, TX+, TX-) plus ground (GND). RS485 half duplex supports a two wire interface (DX+, DX-) plus ground (GND). Each channel has 256 byte transmit and receive FIFOs to significantly reduce the overhead required to provide data to and get data from the transmitters and receivers. The FIFO trigger levels are programmable and the baud rate is individually programmable up to 1 Mbps for RS232 channels and 10 Mbps for RS422/RS485 channels. The UART offers readable FIFO levels. All serial channels use ESD protected transceivers. ESD protection is up to ±15KV.
